Description

The technology disclosed in this specification relates to refrigerators.

Refrigerators are known that are provided with gaskets for sealing between the periphery of the front opening of a storeroom provided in a main body and a door that opens and closes the front opening. Typically, the gasket is secured by engaging a groove in the underside of the door. When the door closes the front opening, the gasket seals between the periphery of the front opening and the rear surface of the door, thereby suppressing leakage of cold air from inside the storage chamber to the outside space.

Also known is a refrigerator in which a heat insulating material is provided in the inner space of the door. This reduces the inflow of heat into the interior of the storage chamber, and suppresses the temperature rise in the interior of the storage chamber.

This specification provides a technique capable of improving the heat insulation performance of a refrigerator.

A refrigerator disclosed herein includes a main body, a door, and a gasket. The door opens and closes a front opening of a storage compartment provided in the body. The gasket seals between the back surface of the door and the peripheral edge of the front opening, and has an engaging portion that engages with a groove provided on the back surface of the door. When the main body is viewed from the front, the opening of the groove is located closer to the front opening of the storage chamber than the portion of the rear surface of the door that is positioned closer to the outer circumference of the main body than the groove. there is

In the above-described refrigerator, the opening of the groove is positioned closer to the front opening (back side in the depth direction of the refrigerator) than the portion of the rear surface of the door that is positioned closer to the outer circumference of the main body than the groove. Therefore, compared to the conventional structure in which the position of the opening of the groove substantially coincides with the position of the rear surface of the door, the area where the groove enters the inner side of the door becomes smaller on the outer peripheral side of the main body than the groove. That is, it is possible to secure a large internal space of the door. Therefore, more heat insulating material can be filled in the inner space of the door than in the conventional case. Therefore, the heat insulation performance of the refrigerator can be improved.

The portion P1 is coupled to a side member 44, which will be described later. A portion P2 located closer to the center of the main body than the groove 70 on the rear surface of the right door 30b is connected to the opening 70a of the groove 70. As shown in FIG. That is, the portion P2 extends from substantially the same position as the opening 70a toward the center of the main body 12 in the depth direction (vertical direction in the drawing). The portion P2 is a range from a portion adjacent to the groove portion 70 (opening portion 70a) on the central side of the main body of the groove portion 70 until it is bent rearward.

The surface member 40 is composed of, for example, a glass plate. Cap members 42 made of synthetic resin (only the upper cap member 42 is shown in FIG. 3) are attached to the top, bottom, left, and right outer peripheral ends of the surface member 40, respectively. Four side portions of the surface member 40 are held by these four cap members 42 .

The side member 44 is made of synthetic resin, for example. Cap members 46 made of synthetic resin (only the upper cap member 46 is shown in FIG. 3) are attached to the upper and lower ends of the side member 44, respectively. That is, the right door 30b is capped with different cap members 42 and 46 at a surface member 40 located on the front surface and a side member 44 located on the side surface, respectively.

The side member 44 is provided with a protruding portion 31 that protrudes rearward from the portion P1 on the outer edge of the side member 44 on the pivot side (that is, on the outer peripheral side of the main body) and on the back surface of the right door 30b. The protruding portion 31 is provided with an inclined portion 31a in which the width of the protruding portion 31 (the length in the horizontal direction of the drawing) gradually decreases from the outer peripheral side of the main body. A space is provided between the tip of the projecting portion 31 and the peripheral portion 15 of the front opening portion 14a. Perimeter 15 is the front surface of body 12 including flanges 36, 39 surrounding front opening 14a. Although the distance L of the interval is not particularly limited, it is, for example, less than 5.6 mm. Further, the tip of the protruding portion 31 is located behind the position of the front surface of the magnet 54, which will be described later, and when the refrigerator 10 is viewed from the side, a member (for example, 3rd projection part 67 grade|etc., which carries out) are comprised so that it may hide.

The vegetable compartment 16, the ice making compartment 18, the upper freezer compartment 20 and the lower freezer compartment 22 are provided with drawer doors 16a, 18a, 20a and 22a, respectively. The front portion of each door 30a, 30b, 16a, 18a, 20a, 22a is covered with a glass plate.

(Structure of Gasket 50)
Refrigerator 10 also includes a gasket 50 disposed between main body 12 and right door 30b, as shown in FIG. Although the gasket 50 for the right door 30b is shown in FIG. 3, a similar gasket 50 is also arranged for the left door 30a. Illustration of the gasket 50 for the left door 30a is omitted.

The gasket 50 is attached to the back surface of the right door 30b (that is, the surface on the main body 12 side). The gasket 50 seals between the rear surface of the right door 30b and the peripheral edge portion 15 of the front opening 14a of the refrigerator compartment 14. As shown in FIG. The gasket 50 is provided so as to make a circuit between the rear surface of the right door 30b and the peripheral portion 15. As shown in FIG. The gasket 50 is formed, for example, by extruding a synthetic resin material such as polyvinyl chloride. As shown in FIG. 4, the gasket 50 includes an engaging portion 52, a magnet 54, a magnet accommodating portion 56, a first connecting portion 58, a second connecting portion 60, a third connecting portion 62, and a fourth A connection portion 63 , a first projection portion 64 , a second projection portion 66 and a third projection portion 67 are provided.

The engaging portion 52 engages with a groove portion 70 provided on the back surface of the right door 30b to fix the gasket 50 to the right door 30b. When the engaging portion 52 engages the groove portion 70 , the base portion 52 a of the engaging portion 52 closes the opening portion 70 a of the groove portion 70 .

The magnet 54 is accommodated in the magnet accommodating portion 56, and contacts the peripheral edge portion 15 (flange portion 36 of the outer casing 12a) of the front opening portion 14a when the right door 30b is closed. The magnet 54 is formed such that its length in the thickness direction (vertical direction in the drawing) is longer than its length in the width direction (horizontal direction in the drawing). Also, the magnet 54 is provided so as to be located closer to the outer circumference of the main body than the groove 70 when the main body 12 is viewed from the front. In other words, when the main body 12 is viewed from the front, the magnet 54 is offset from the groove portion 70 toward the outer periphery of the main body.

The first connecting portion 58 connects the base portion 52 a of the engaging portion 52 of the gasket 50 and the magnet accommodating portion 56 . The first connecting portion 58 extends from the rear side of the surface of the magnet accommodating portion 56 on the center side of the main body. The first connecting portion 58 has a first curved portion 58a that curves toward the center of the main body. Specifically, the first connecting portion 58 extends from the magnet accommodating portion 56 toward the center of the main body, crosses over the groove portion 70, and then extends from the center of the main body through the first curved portion 58a that curves forward. is connected to the base 52a of the That is, both ends of the first connecting portion 58 are connected to the magnet accommodating portion 56 and the base portion 52a of the engaging portion 52 via the first curved portion 58a.

The second connecting portion 60 connects the base portion 52 a of the engaging portion 52 of the gasket 50 and the magnet accommodating portion 56 . The second connecting portion 60 is the surface of the magnet accommodating portion 56 on the central side of the main body and extends forward from the first connecting portion 58 . The second connecting portion 60 has a second curved portion 60a that curves toward the center of the main body. Specifically, the second connecting portion 60 extends from the magnet accommodating portion 56 to the outer peripheral side of the main body through the second curved portion 60a that curves forward in the vicinity of the opening 70a of the groove portion 70 on the outer peripheral side of the main body. It is bent toward the center of the body and connected to the base portion 52 a of the engaging portion 52 .

The third connecting portion 62 connects between the base portion 52 a of the engaging portion 52 and the first connecting portion 58 . The third connecting portion 62 extends linearly in the thickness direction (vertical direction in the drawing) of the gasket 50 at the central position of the engaging portion 52 in the horizontal direction.

The fourth connecting portion 63 connects between the base portion 52 a of the engaging portion 52 and the first connecting portion 58 on the central side of the main body relative to the third connecting portion 62 . The fourth connecting portion 63 has a fourth curved portion 63a curved toward the center of the main body.

The inside of the gasket 50 is divided by the base portion 52a, the magnet housing portion 56, the first connecting portion 58, the second connecting portion 60, the third connecting portion 62, and the fourth connecting portion 63 described above. It is divided into a bag-shaped portion 92 and a third bag-shaped portion 94 . An air layer is formed inside each of the bag-like portions 90 , 92 , 94 . Specifically, the first bag-like portion 90 is a space defined by the magnet housing portion 56 , the first connecting portion 58 , the third connecting portion 62 , the base portion 52 a and the second connecting portion 60 . The second bag-shaped portion 92 is a space defined by the first connecting portion 58 , the fourth connecting portion 63 , the base portion 52 a and the third connecting portion 62 . The third bag-shaped portion 94 is a space defined by the first connecting portion 58 , the base portion 52 a and the fourth connecting portion 63 .

When the right door 30b is changed from the open state to the closed state, as shown in FIG. It is pressed by the flange portion 36 of the box 12a and the flange portion 39) of the inner box 12b. Thereby, the space between the rear surface of the right door 30b and the peripheral edge portion 15 of the front opening portion 14a is sealed. As a result, the internal space S1 of the refrigerator 10 is insulated from its external space S2.

The first projecting portion 64 protrudes from the first curved portion 58a toward the center of the main body. The second protrusion 66 protrudes toward the center of the main body from behind the first protrusion 64 of the first curved portion 58a. The first projecting portion 64 and the second projecting portion 66 extend like fins from the first curved portion 58a toward the center of the main body. FIG. 5 is an enlarged cross-sectional view of the periphery of the first projection 64 and the second projection 66. As shown in FIG. As shown in FIG. 5, the thickness of the first connecting portion 58 in the range A1 between the first protrusion 64 and the second protrusion 66 is thinner than the thickness of the first connecting portion 58 in other portions. Further, the third projecting portion 67 protrudes from the front surface of the magnet housing portion 56 to the rear surface side of the right door 30b.

As shown in FIG. 6, when the gasket 50 is released from the external force (that is, when the right door 30b is open), the rear end of the first connecting portion 58 is positioned behind the rear surface of the magnet accommodating portion 56. ing. In other words, the rearmost positions of the bag-like portions 90 , 92 , 94 are located behind the magnet accommodating portion 56 . When the right door 30b switches from the open state to the closed state (switches from the state shown in FIG. 6 to the state shown in FIG. 3), the gasket 50 (the first connecting portion 58) moves along the peripheral edge as indicated by an arrow Y1. It is pressed by the portion 15 and deformed. At this time, as indicated by an arrow Y2, the first protrusion 64 transitions to the back side of the right door 30b and contacts the back member 48 of the right door 30b on the center side of the main body from the groove 70. As shown in FIG. Also, as indicated by an arrow Y3, the second protrusion 66 transitions toward the main body 12 and comes into contact with the inner box 12b. Also, as indicated by an arrow Y4, the third protrusion 67 contacts the side member 44 of the right door 30b.

(effect)
In the refrigerator 10 of this embodiment, the position of the opening 70a of the groove 70 is positioned rearward (toward the front opening 14a) of the portion P1 on the outer peripheral side of the main body of the back surface of the right door 30b. As a result, the area in which the groove portion 70 enters the inside of the right door 30b is reduced, so that a large internal space of the right door 30b can be ensured. Therefore, it is possible to increase the amount of heat insulating material filled in the internal space of the right door 30b. A portion P2 located closer to the center of the main body than the groove 70 on the back surface of the right door 30b extends toward the center of the main body from substantially the same position as the opening 70a of the groove 70 in the depth direction of the main body 12 . Therefore, the internal space of the right door 30b on the central side of the main body relative to the groove 70 can be widely utilized, and the space can be filled with a large amount of heat insulating material. Therefore, in the refrigerator 10 of the present embodiment, the inflow of heat into the refrigerator 10 is reduced, and the heat insulation performance of the refrigerator 10 can be improved. In addition, since the portion P2 is generally located closer to the center of the main body than the center 96 of the pivot shaft 96 of the hinge member 34, the distance between the portion P2 and the peripheral portion 15 does not decrease when the right door 30b is opened or closed ( See Figure 7). Therefore, even if the portion P2 is located at substantially the same position as the opening 70a of the groove 70 in the depth direction of the main body 12, they do not interfere with each other.

In addition, in the depth direction of the main body 12, the position of one of the openings 70a of the groove 70 (the center side of the main body) substantially coincides with the position of the back surface of the right door 30b. The positioned members (grooves 70, portions P1, P2, etc.) can be easily manufactured by injection molding.

Further, in the refrigerator 10 of the present embodiment, the first connecting portion 58 and the second connecting portion 60 respectively have a first curved portion 58a and a second curved portion 60a curved toward the center of the main body. Furthermore, the fourth connecting portion 63 similarly has a fourth curved portion 63a curved toward the center of the main body. In this way, since each connecting portion has a portion that curves toward the center of the main body, it is possible to sufficiently ensure flexibility in the opening/closing direction of the right door 30b.

In addition, in the gasket 50 of the present embodiment, since all the connecting portions 58, 60, 62, 63 extending from the magnet accommodating portion 56 all extend from the surface of the magnet accommodating portion 56 on the central side of the main body, the magnet accommodating portion 56 faces the exterior space S2. Magnets 54 are generally more thermally conductive than air. Therefore, the magnet 54 reduces the temperature of the refrigerant on the way from the compressor to the cooler and increases the temperature of the outer surface of the main body 12 to absorb the heat emitted from the heat radiation pipe 80 to prevent condensation. This promotes the transmission to the inside of the refrigerator 10. However, in the present embodiment, since most of the magnet housing portion 56 faces the exterior space S2 of the refrigerator 10, the heat radiation to the exterior space S2 side is more dominant than that to the interior space S1 side of the refrigerator 10. Inflow of heat into 10 can be suppressed.

In addition, in this embodiment, the magnet 54 is located closer to the outer circumference of the main body than the groove 70 when the main body 12 is viewed from the front. Therefore, the thickness of the entire gasket 50 can be reduced compared to a configuration in which the groove portion 70 and the magnet 54 overlap when the main body 12 is viewed from the front. Furthermore, in the gasket 50 of the present embodiment, since the magnets 54 are offset with respect to the grooves 70, the thickness of the portions (the bag-like portions 90, 92, 94, etc.) closer to the center of the body than the magnets 54 is reduced. At the same time, the thickness of the magnet 54 can be secured, and sufficient magnetic force of the magnet 54 can be secured. Moreover, even if the temperature of the magnets 54 with high thermal conductivity rises, the heat of the magnets 54 is less likely to flow into the refrigerator 10 because the magnets 54 are positioned on the outer peripheral side of the main body. Moreover, since the contact area between the entire bag-shaped portions 90, 92, and 94 of the gasket 50 and the magnet housing portion 56 is small, heat is less likely to be conducted to the inner space S1 side.

In the closed state of the right door 30b, the space S3 is formed by the contact of the first projection 64 with the rear surface of the right door 30b, and the space S4 is formed by the contact of the second projection 66 with the inner box 12b. A space S5 is formed by contacting the side member 44 with the third protrusion 67 . Thus, in the closed state of the right door 30b, in addition to the bag-like portions 90, 92, 94, air layers shown in the spaces S3 to S5 are formed. Therefore, the heat conductivity of the entire gasket 50 can be further reduced, and the heat insulation performance of the refrigerator 10 is further improved.

In addition, the thickness of the range A1 between the first projection 64 and the second projection 66 of the first connecting portion 58 is thinner than the thickness of the other portions. Therefore, when the right door 30b is closed and the bag-like portions 90, 92, 94 are pressed, the deformation of the gasket 50 in the range A1 becomes greater than that in the other portions. Therefore, the angles of the first protrusion 64 and the second protrusion 66 can be easily changed, and the protrusions 64 and 66 can be preferably brought into contact with the respective surfaces.

Further, the first connecting portion 58 and the base portion 52 a of the engaging portion 52 are connected by a linear third connecting portion 62 . Therefore, when the right door 30b is opened, the magnet 54 can be efficiently separated from the peripheral edge portion 15 by the third connecting portion 62 .

Further, as shown in FIG. 7 , generally, the rotation axis center 96 of the hinge member 34 is provided closer to the center of the main body than the outermost side surface of the refrigerator 10 . Therefore, as shown in FIG. 7, in the process of opening and closing the door, the distance between the rear surface of the door and the peripheral edge portion 15 is closer by a distance L1 than the distance L between the rear surface of the door and the peripheral edge portion 15 in the closed state. timing occurs. In the refrigerator 10 of the present embodiment, the protruding portion 31 provided on the back surface of the right door 30b has an inclined portion 31a, so that the tip of the protruding portion 31 (the portion closest to the peripheral edge portion 15 in the closed state) is positioned on the right side. It is located closer to the center of the main body than the outermost side of the door 30b. Therefore, in the process of opening and closing the right door 300b of the refrigerator 100 of the comparative example (refrigerator whose side surface of the right door 300b extends rearward linearly) shown in FIG. In the process of opening and closing the right door 30b, the distance L1 at which the right door 30b approaches the peripheral portion 15 is shorter than the distance L2 at which the right door 30b approaches the peripheral portion 115 . Since the tip of the protruding portion 31 and the peripheral portion 15 are less likely to interfere with each other as compared with the conventional art, the distance L can be set short. By setting the distance L short, it is possible to prevent the user's finger from entering the gap between the right door 30b and the main body 12 .

Further, by positioning the tip of the projecting portion 31 closer to the center of the main body than the heat radiation pipe 80, the path from the heat radiation pipe 80 to the internal space S1 of the refrigerator 10 is narrowed. 10 can be efficiently discharged to the outside space S2 side.

Further, in the refrigerator 10 of the present embodiment, the distance L between the tip of the protruding portion 31 and the peripheral edge portion 15 is 5.6 mm as a finger probe (JIS C 0922, probe cord 19, IEC 61032). Therefore, children's fingers are prevented from entering between the right door 30b and the main body 12, thereby improving safety.

The right door 30b has a surface member 40 covering the front surface and a side surface member 44 provided on the side surface, which are capped with different cap members 42 and 46, respectively. Therefore, manufacturing is easier than when the right door 30b is integrally formed.

While several embodiments of the invention have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the scope of the invention paper.

In the above-described embodiment, the gasket 50 is attached to the grooves 70 provided on the rear surfaces of the double doors 30a and 30b. A gasket as described herein may be installed. Further, the side member 44 of the right door 30b does not have to have the projecting portion 31 .
